Abstract

An end effector for use with a surgical apparatus. The end effector comprising a staple cartridge having a tissue contacting surface defining a central longitudinal slot and an anvil plate having a tissue contacting surface defining a central longitudinal slot. A folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and anvil plate and configured to retain the surgical buttress to the tissue contacting surfaces of each of the staple cartridge and anvil plate. The surgical buttress having a first longitudinal portion, a second longitudinal portion, and middle longitudinal portion between the first and second longitudinal portions, wherein the middle longitudinal portion is folded and configured to fit within the central longitudinal slot of each of the staple cartridge and anvil plate.

Claims

1. An end effector for use with a surgical apparatus, the end effector comprising:

a staple cartridge having a tissue contacting surface defining a central longitudinal slot;

an anvil plate having a tissue contacting surface defining a central longitudinal slot; and

a folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and anvil plate and configured to retain the surgical buttress to the tissue contacting surfaces of each of the staple cartridge and anvil plate, the surgical buttress defining a bottom surface, and including a proximal portion with a proximal edge and a distal portion with a distal edge,

wherein at least one of the proximal portion and the distal portion is folded with respect to the bottom surface.

2. The end effector according to claim 1, wherein the surgical buttress has a first longitudinal portion, a second longitudinal portion and middle longitudinal portion between the first and second longitudinal portions,

wherein the middle longitudinal portion is folded and configured to fit within the central longitudinal slot of each of the staple cartridge and anvil plate.

3. The staple cartridge of claim 2, wherein the middle longitudinal portion is substantially V-shaped.

4. A staple cartridge for use with a surgical stapling apparatus, the staple cartridge comprising:

a cartridge body including a tissue contacting surface defining a plurality of staple retaining slots and having a central longitudinal slot;

a staple disposed within each staple retaining slot of the cartridge body; and

a folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and configured to retain the surgical buttress to the tissue contacting surface of the staple cartridge, the surgical buttress defining a bottom surface, and including a proximal portion with a proximal edge and a distal portion with a distal edge,

wherein the proximal portion is folded in the direction of the bottom surface such that the proximal edge is adjacent the bottom surface of surgical buttress,

wherein the distal portion is folded in the direction of the bottom surface such that the distal edge is adjacent the bottom surface of surgical buttress.

5. A surgical stapling apparatus, comprising:

a housing; and

the staple cartridge according to claim 4.

6. A surgical stapling apparatus, comprising:

a housing;

an end effector being secured to the housing having a staple cartridge assembly having a tissue contacting surface and an anvil assembly having a tissue contacting surface, each of the staple cartridge assembly and anvil assembly having a central longitudinal slot; and

a folded surgical buttress configured to overlie each of the tissue contacting surfaces of the staple cartridge and anvil plate and configured to retain the surgical buttress to the tissue contacting surfaces of each of the staple cartridge and anvil plate, the surgical buttress has a first longitudinal portion, a second longitudinal portion and middle longitudinal portion between the first and second longitudinal portions, the surgical buttress defining a bottom surface, and including a proximal portion with a proximal edge and a distal portion with a distal edge,

wherein the proximal portion is folded in the direction of the bottom surface such that the proximal edge is adjacent the bottom surface of surgical buttress,

wherein the distal portion is folded in the direction of the bottom surface such that the distal edge is adjacent the bottom surface of surgical buttress.
